This implementation plan facilitates the execution of the initial project plan by defining the roadmap as well as the technologies used in each of the AI4EOSC phases. To follow a good implementation strategy, this document will explain the project objectives and a timeline of the tasks carried out for the implementation of the Experiment Centric AI Services. This deliverable provides a timeline with the details of the steps of the AI4EOSC experiment centric and composite-AI release 1 published in M18 and release 2 by the end of M33 and when they will be implemented. This is a preliminary plan subject to modification during the course of the project, as some components, and their corresponding tasks, will certainly evolve during the project also in accordance with the user feedback collected in WP6.
